Question 163679: Hi....I am having a really hard time with word problems. I am not sure how to make this into an equation. Please help!!!
When will Johnson be twice as wealthy as Smith if each has $4000 now and if their estates are increasing at the annual rates of $400 for Smith and $1200 for Johnson?

You can put this solution on YOUR website!
let w=wealth and y=years

Johnson __ w=1200y+4000

Smith __ w=400y+4000

2(400y+4000)=1200y+4000 __ 800y+8000=1200y+4000 __ 4000=400y __ 10=y
